Adaptative Body Bias IP
Adaptative Body Bias (ABB) IP

A revolutionary FD-SOI bias generator enabling real-time corner compensation:
- Up to 10x energy efficiency gains at low VDD
- Foundation IP independent
- Seamless integration

A revolutionary IP enabling real-time control of transistor threshold voltages

The all-in one Dolphin ABB IP features a bias generator, low power sensors, and a control loop to enable  on-the-fly  adaption of transistor threshold voltages.

Efficient compensation of all process, voltage, temperature, and aging variations can be performed in real time, while the circuit is operating. Combined with ABB-aware libraries significant PPA gains can be achieved.

The area of the ABB IP system is marginal (<1%) as well as the power consumption (34µW in TT, 25° C)

The ABB IP is compatible with all foundation libraries and is available in GLOBALFOUNDRIES 22FDX® technology.

Outstanding energy efficiency gains

Thanks to our ABB IP, designers can relax the timing constraints imposed by the different corners during circuit implementation.

Process, Voltage and Temperature variation window can be drastically reduced, leading to significant PPA gains.

10x speed improvement on an ARM® Cortex®-M4 based on GLOBALFOUNDRIES 22FDX® has been demonstrated at low VDD.

Significant speed gains ranging from +40% to +220% have also been proved at nominal VDD

Take advantage of ABB benefits TODAY

The ABB IP version targeting ULP IoT & middle performance SoC is available today in GLOBALFOUNDRIES 22FDX® technology.

Two more versions are being deployed targeting Automotive & High Performance applications with options to compensate aging variations for enhanced circuit reliability.
